U.S. spot crypto ETF flows diverged sharply last week: Ethereum spot ETFs saw roughly $140 million in net outflows, ending four consecutive weeks of inflows, with BlackRock's ETHA posting over $56 million in weekly outflows; Bitcoin spot ETFs recorded $6.21 million in net inflows, with BlackRock's IBIT attracting $121 million. Disclosed regulatory and institutional moves in the same period — including the SEC advancing exemptions for tokenized-stock trading and RCA fundraising rules, Russia's central bank proposing to cap banks' crypto exposure at 1% of own capital, and Apple and Google hiring stablecoin-related talent — together form a broader backdrop for observing institutional crypto allocation.
U.S. spot crypto ETFs saw a clear divergence in fund flows last week. Ethereum spot ETFs flipped from four consecutive weeks of net inflows to an aggregate net outflow of roughly $140 million. Bitcoin spot ETFs, meanwhile, continued to post net inflows, bringing in about $6.21 million for the week, a limited absolute amount but keeping the flow direction positive. The divergence was centered on two BlackRock products: IBIT, which tracks Bitcoin, saw net inflows of $121 million, while ETHA, which tracks Ethereum, saw net outflows of over $56 million. The two flagship crypto asset spot ETFs moved in opposite directions in the same period.
In terms of institutions and products, the latest flow data primarily covers U.S. spot Bitcoin ETFs and spot Ethereum ETFs. Ethereum spot ETFs recorded total net outflows of $140 million, snapping a four-week streak of net inflows; Bitcoin spot ETFs logged net inflows of $6.21 million. Beyond ETF flow data, recently disclosed materials also showed several regulatory and institutional developments: the U.S. SEC has made a significant shift in its stance toward tokenized assets, involving exemptions for tokenized-stock trading and rules for RCA fundraising, offering a compliance path for the industry. Russia's central bank has proposed a draft rule capping banks' crypto exposure at 1% of their own capital. Apple and Google have begun hiring for stablecoin and tokenized deposit-related roles, exploring new payment businesses. These items have not yet been detailed with implementation timelines, but together they form important background for understanding current institutional participation in crypto assets.
Looking at the breakdown for Ethereum spot ETFs, the four-week net inflow run came to an end last week. The roughly $140 million total net outflow represented a directional reversal from the prior streak. Among the individual products disclosed, BlackRock's ETHA posted weekly net outflows of more than $56 million. Based on the disclosed figures, if ETHA's outflow was at least $56 million against an overall outflow of about $140 million, ETHA accounted for more than 40% of the total net outflow, making it one of the largest disclosed outflow contributors. It should be noted that the original material did not list a full product-by-product breakdown, so only a comparison between ETHA and the aggregate can be made; no inferences can be drawn about the specific subscription and redemption directions of every other Ethereum spot ETF. The flip from inflows to outflows reflects a short-term shift in institutional sentiment toward ETH, and this shift has a direct impact on market sentiment.
For Bitcoin spot ETFs, total net inflows came to $6.21 million last week, contrasting with the Ethereum spot ETFs in terms of flow direction. Among them, BlackRock's Bitcoin spot ETF IBIT attracted $121 million in the week, a standout among comparable products. Placing IBIT's $121 million inflow alongside the overall $6.21 million inflow implies that other Bitcoin spot ETF products recorded a combined net outflow of approximately $114.8 million. This figure is derived by calculating the difference between the overall net inflow and IBIT's net inflow; it is an analytical inference, as the original material did not disclose flows for each of the other products individually. The gap indicates that significant divergence exists within Bitcoin spot ETFs themselves, with the top product's inflows not fully translating into a larger overall net inflow. In terms of magnitude, the roughly $6.21 million net inflow for Bitcoin spot ETFs and the roughly $140 million net outflow for Ethereum spot ETFs are not on the same scale, showing a substantial difference in the size of their flows.
Taken together, the divergence focused on BlackRock's two spot products: IBIT, tracking Bitcoin, saw net inflows of $121 million, while ETHA, tracking Ethereum, saw net outflows of over $56 million. The same issuer recorded opposite subscription and redemption directions across its Bitcoin and Ethereum spot products in the same period, providing the most direct comparison in this round of spot ETF data. This comparison indicates that institutional capital has not broadly exited crypto asset spot ETFs, but has instead made a directional adjustment between the two major asset classes, Bitcoin and Ethereum.
Two further observations can be drawn from the data. First, Ethereum spot ETFs saw total net outflows of $140 million, with ETHA alone accounting for more than $56 million of that, indicating the outflows were not evenly distributed across products but were somewhat concentrated. Second, Bitcoin spot ETFs posted overall net inflows of just $6.21 million, yet IBIT alone brought in $121 million; calculating the difference leaves roughly $114.8 million in combined net outflows for other products, showing that a redistribution of funds among products is also occurring within Bitcoin ETFs. Together, the two signals show that institutional capital is undergoing structural adjustment across major crypto assets and different products, rather than a broad one-way inflow or outflow.
During the same period as the ETF flow divergence, regulators and large institutions also took noteworthy steps in crypto assets. The U.S. SEC made a significant shift in its approach to tokenized assets, covering exemptions for tokenized-stock trading and RCA fundraising rules, offering a compliance path for the industry. Russia's central bank proposed a draft that would cap banks' crypto asset exposure at 1% of own capital, a signal of tighter policy at the national level. Apple and Google, the two tech giants, have started hiring for stablecoin and tokenized deposit roles, a clear sign that traditional payment majors are exploring crypto infrastructure. These developments all come from disclosed public materials; specific timelines and implementation details have not yet been fully laid out. Still, they show that beyond spot ETF flows, areas such as tokenized assets and stablecoin payments continue to attract attention from regulators and large institutions, and together with spot ETF flows form an important backdrop for observing institutional allocation to crypto assets.
Several directions are worth monitoring going forward. First, whether Ethereum spot ETFs can return to net inflows, with changes in BlackRock's ETHA directly affecting the overall figures. Second, whether Bitcoin spot ETFs can expand their overall net inflows on the back of continued strength in IBIT, and whether aggregate net outflows from other products will persist. Third, whether the divergence between Bitcoin and Ethereum spot ETF flows is a temporary phenomenon or a longer-term shift; next period's flow data will offer further clues. Fourth, whether progress on the SEC's exemptions for tokenized-stock trading and the RCA fundraising rules will affect institutional willingness to participate in tokenized assets. Fifth, the subsequent advancement and revisions to the Russian central bank's draft on limiting banks' crypto exposure, as well as whether Apple and Google's stablecoin-related hiring translates into concrete payment businesses, are also worth monitoring. The above is compiled from disclosed weekly flow data and public materials and does not constitute investment advice.
